To construct buildings or train units, click on one of your regions on the world map. This opens the region panel where you can select what to build.

Each region has a limited amount of building space (default 1000). Buildings and units take up space, cost resources (Cash, Wood, Steel, Food), and take time to complete. You can cancel constructions in progress.

There are several categories of buildings and units you can construct:

Buildings

• Economic Center — Generates cash income
• Farm — Generates food
• Iron Mine — Generates steel
• Woodcutter — Generates wood
• House — Provides population, which brings in cash and crews the units you train
